While the problem is fascinating, and the solution is out of my expertise, I will say this:

I'm concerned that this is a mild scam. The indiegogo project is listed as a "flexible goal", which is described like this: "This campaign will receive all funds raised even if it does not meet its goal".

This type of project surely needs a bare minimum to even get a prototype going. If you get someone to pledge $30, and nobody else pledges anything, you've just got yourself a free $30. You don't even have to produce anything in exchange for that $30, it's yours to run with.

Given that the goal is flexible and he'll likely run away with whatever small amount you give, I would advise all posters to refrain from contributing to this. If it was a non-flexible goal I might not say anything and let it fly.
